New method could help quantify untapped natural gas reservoirs
More than 30 states have shale formations that harbor natural gas underground, according to the Energy Information Administration. But industry experts can’t agree on exactly how much fuel is inside. That’s because natural gas and other hydrocarbons lie inside nano-scale, difficult-to-measure pores in shale rocks, which have properties that are not yet understood. “If you want to estimate the storage capacity of shale gas, you need to understand materials that store them,” said Yun Liu, an affiliated associate professor of chemical engineering at the University of Delaware and a physicist at the National Institute of Standards and Technology (NIST) Center for Neutron Research.
